Abstract

The invention discloses a dopamine-based modified overhaul slag and a preparation method and application thereof, and belongs to the technical field of green resource recycling of solid waste, including: adhering a poly-dopamine coating on the surface of overhaul slag powder through the self-polymerization reaction of dopamine, and then grafting a functional group with hydrophobic function on the surface of the coating by a chemical grafting method to form a hydrophobic protective layer, thus obtaining the product, namely the dopamine-based modified overhaul slag, where the substance providing hydrophobic functional groups is gamma-methacryloyloxypropyltrimethoxysilane or octadecylamine. This product can be used as a modifier in asphalt pavement to improve the viscoelasticity and deformation resistance of modified asphalt.
